Well Bellhorn, SSS is a valid problem. It's not an excuse to not have to accept the notion of "clutch". And when that small sample is spread out over several seasons, it becomes even more of a problem.
It's not really so much that stat geeks are saying that "clutch" doesn't exist. To date, however, they have dissected the data pretty much every way humanly possible, and have found no statistical evidence that being a clutch hitter is a repeatable skill. Clutch hits happen all the time, but being "clutch" is not a skill. Another difficulty lies in defining exactly what clutch is.
Bill James even concedes that clutch may exist. There just hasn't been any proof to that effect yet.
